Ashima AiRotor Disc Brake Rotor

The Ashima AI Stainless Steel Rotor is a single-piece, lightweight 6-bolt rotor engineered from high-grade SUS410 stainless steel. Precision machining and large ventilation cut-outs reduce mass and improve heat shedding, while double-ground braking surfaces support parallelism and consistent pad contact. No special pads are required—use with standard organic or metallic compounds. Offered in 140, 160, and 180 mm with verified weights below. with verified weights below; stainless rotor bolts are included.

• road, gravel, CX, and XC where low mass and predictable braking are prioritized.
• (For ultra-light alternatives or 2-piece designs, see Ai2 / AiNeon rotors.)

Install notes: Degrease rotor, use medium threadlocker on bolt threads, tighten in a star pattern to hub/rotor maker torque spec, and bed-in per caliper manufacturer guidance.
